http://www.audiotrak.net/products/prodigyhd2/ This card is compatible with Linux Debian Squeeze after jumper J4 is switched to ON. May be reflash is not needed anymore because my card works fine with firmwares for both VIA and Egosys drivers. It is a very musical card for a half of the Asus Essence ST price. I enjoy it together with a Denon amplifier and Paradigm monitors. You may need to add: options snd-ice1724 model=prodigyhd2 to /etc/modprobe.d/alsa-base.conf
